Estimation of the fossil fuel savings by Low Emission Vehicles (LEVs) requires an estimate of the fuel consumption of ‘equivalent’ internal combustion engine vehicles (ICVs) that have been displaced. Therefore we first constructed a statistical model of standardised vehicle test ‘driving cycle’ measures of fuel consumption of 90 conventional (ICVs) for ‘urban’, ‘ex-urban’ and ‘combined’ driving conditions in New Zealand. The model …….
